Surfactant adsorption at solid surfaces is, in practice, exploited to facilitate detergency, control wetting and penetration of solutions, stabilize foams and emulsions, and collect minerals in flotation operations. From this list alone, it is clear that this field is of tremendous importance. Consequently, significant effort has been directed toward acquiring a better understanding of the adsorptive nature of different surfactant molecules at solid surfaces. ...

In some applications, such as the production of whipped cream, beer, meringue (-+food additives), foamed plastics, ->fire fighting foams, ore-(- mining chemicals) and waste paper-flotation (- paper additives), foamed concrete and - detergents, (controlled) foam formation is desired. Products enhancing this property are called foamers and are - surfactants or - water soluble polymers or mixtures of both. 

A wide class of aiyl-based quaternary surfactants derives from heterocycles such as pyridine and quinoline. The Aralkyl pyridinium halides are easily synthesized from alkyl halides, and the paraquat family, based upon the 4, 4 -bipyridine species, provides many interesting surface active species widely studied in electron donor-acceptor processes. Cationic surfactants are not particularly useful as cleansing agents, but they play a widespread role as charge control (antistatic) agents in detergency and in many coating and thin film related products. 

Alkenylsuccinic anhydrides made from several linear alpha olefins are used in paper sizing, detergents, and other uses. Sulfosuccinic acid esters serve as surface active agents. Alkyd resins (qv) are used as surface coatings. Chlorendric anhydride [115-27-5] is used as a flame resistant component (see Flame retardants). Tetrahydrophthalic acid [88-98-2] and hexahydrophthalic anhydride [85-42-7] have specialty resin appHcations. Gas barrier films made by grafting maleic anhydride to polypropylene [25085-53-4] film are used in food packaging (qv). Poly(maleic anhydride) [24937-72-2] is used as a scale preventer and corrosion inhibitor (see Corrosion and corrosion control). Maleic anhydride forms copolymers with ethylene glycol methyl vinyl ethers which are partially esterified for biomedical and pharmaceutical uses (189) (see Pharmaceuticals). 

The new Uquid laundry detergents, with no phosphates, have developed a use for alkan olamines. In nonenzyme formulations, they contribute alkalinity, pH control, and enhanced product stabiUty. In enzyme products, alkan olamines contribute to the stabiUty of the enzyme in water solutions (107). 

Fabric Softening. The use of quaternary surfactants as fabric softeners and static control agents can be broken down into three main household product types rinse cycle softeners tumble dryer sheets and detergents containing softeners, also known as softergents. Rinse cycle softeners... 

Quahty control testing of siUcones utilizes a combination of physical and chemical measurements to ensure satisfactory product performance and processibihty. Eor example, in addition to the usual physical properties of cured elastomers, the plasticity of heat-cured mbber and the extmsion rate of TVR elastomers under standard conditions are important to the customer. Where the siUcone appHcation involves surface activity, a use test is frequently the only rehable indicator of performance. Eor example, the performance of an antifoaming agent can be tested by measuring the foam reduction when the sihcone emulsion is added to an agitated standard detergent solution. The product data sheets and technical bulletins from commercial siUcone producers can be consulted for more information.
